Granulated Material Used In A Liquid Composite Moulding Process

A system for liquid composite moulding, the system comprising:

• a first rigid tool part;
• a first vacuum foil;
• a second vacuum foil;
• and
• a granulated material;
• wherein the first vacuum foil is arrangeable in such a way on the first rigid tool part that a first gastight chamber is provided between the first vacuum foil and the first rigid tool part;
• wherein a first port is provided at the first gastight chamber in such a way that a semi-finished fiber material positioned between the first rigid tool part and the first vacuum foil is infusible with a matrix material via the first port;
• wherein between the first vacuum foil and the second vacuum foil a second gastight chamber is provided in which the granulated material is arranged;
• wherein a second port is provided at the second gastight chamber for applying a negative pressure to the second gastight chamber;
• and
• wherein the granulated material is adapted for forming a second rigid tool part when negative pressure is applied to the second port.
